How to Draw the Rib Cage - Human Anatomy for Artists

[@SabreanaOlson]

I actually had a huge "OHHH!" moment at the end with the "ant trail". I have never understood so easily before. Thank you so much for your videos dude.

[@kamakozy13]

Man Proko, I'll tell everybody. You dah man.

[@ProkoTV]

Azawa Medkour Thanks ;)

[@celestinenwachukwu3440]

There are many components to studying anatomy. One place I found that successfully combines these is the Sebs Study Crammer (check it out on google) definately the most helpful course that I have ever seen. look at this extraordinary website.

[@elsevillaart]

This videos just make me want to grab a pencil right now, the medic gave me a prescription and means more proko.

[@FerdandOfThe]

Hey Stan, do you think that you'll ever have something on how to draw kids? I realize that a lot of the anatomy from your videos would still apply, but I'm just curious about what you feel is important in that area that's different from drawing adults. Still loving the anatomy videos, though. They've been helping a ton.

[@ProkoTV]

Ferdand of the Underworld In my future "Advanced Portrait Drawing" course I will teach drawing kids heads. As for drawing kids bodies.. Maybe something in a future figure drawing or illustration course. But I don't think I'll do "Anatomy of kids".

[@FerdandOfThe]

Proko That's just what I was wondering. Thank you very much for responding! I hope you keep up the great work, too!

[@advg39]

Proko Proko you rock-o thanks for all the energy and thought and well everything you putting on those videos seriously great job. I used to have a big problem with my poses their body motion looked like frozen ugly bodies with details and well i wanted to look them to look more dynamic and natural your videos especially the spine and the rib cage videos was amazing they helped me to improved a lot still not mastered it far away from that goal but well iam in a good way. thx a gain keep doing what you like .

[@ulmcneill2011]

i really like your videos mr proko. all of your videos keep being useful even when i avoid using them. they save time from sifting through countless anatomy studies that a lot of the time dont explain as much.

[@CS-jk1mt]

Interesting to note: at 1:37 he mentions that the bottom of the sternum (minus the xiphoid process) is halfway between pit of the neck and the bottom of the ribcage. At 2:26 he adds the xiphoid process.

[@edwardartetv]

Proko, I admire your artworks, you are a master, my friend. You got a bless from the Gods !

[@ziolekanimations2312]

I thought ribcage was easy , yeah its not

[@laperraquehabla]

this is mindblowing bless you Proko!

[@mudassarartwork]

you are teacher for millions

[@Adrimixmi]

This feels so much easier than the pelvis! I still struggle to draw everything right, the spine is not that easy, but it's manageable, but I grew tired of trying to draw pelvises (do you say that?! x), so I moved on, and man, that feels do to draw something that looks right!

[@yevmann]

Yeah, the pelvis is pretty tricky. It's very complex.

[@allluckyseven]

Thanks, Proko. I'm having a bit of a hard time trying to visualize what's happening when you draw that line that goes from the back of the ribcage to the sternum, at 6:59 Shouldn't the line follow the bottom contour of the "box", which goes more to the left?

[@ProkoTV]

allluckyseven Good question, I can see how that's confusing. The box form is a simplified version of the overall volume to show the structure better. The lines of the box follow the planes. The curve to the sternum follows the tips of the bottom ribs (which curve toward the front plane more) and then along the edge of the cartilage (thoracic arch).

[@reymiyamoto5717]

Thank U for good lessons!

[@jefersondeoliveiranunes2710]

I relly like your videos, Im learn so much, thanks!!!

[@rjuriklodhbrok546]

Do we really need to draw the details of the skeleton when we're drawing a figure or just the shapes will suffice?

[@samy7342]

It depends on the model or figure ur drawing.

[@clearlyblurry508]

Hmm, I figured I'd see more comments. This is such a helpful video, even today!

[@bruhbro9813]

that censor bar tho hahahhaha this is why your one of the best drawing ytber

[@Sarsange]

thank you so much!

[@jamqdlaty]

I thought the thoracic section of the spine rotates around it's axis. It's possible to rotate chest around 45 dgr and most of it is in the thoracic section, so I don't get why you never show the rotation on drawings. 4:05 photo is a perfect example of pushing t he rib cage rotation to the limits and that sketch on the right side looks nothing like what's on the photo. :( 5:43 - Not really... It's a bit exaggerated, but just slightly. That's exactly the curve you'd expect from rotating this part of spine around it's axis.

[@PikesCore24]

Shaggy, you are correct. The rib cage does twist and bend. In fact, in the world of weight lifting, you can find numerous videos on the subject of increasing Thoracic extension, which means increasing the range of movement to bend your thoracic spine backwards. Weight lifters need this flexibility in order to lift a bar straight over their head. If the Thoracic spine extends, then the rib cage must also bend. So it is frustrating that in the field of drawing, everyone assumes the rib cage doesn't bend or twist.

[@MultiTrace22]

Could you make a Self-portrait?! That should be interesting!

[@RekhaYadav-jk8td]

Very good

[@ryanmulherin2682]

The rib cage goes SNAP SNAP SNAP!

[@carriewu7428]

Hi Stan. Your lessons are really inspirational and I learnt a lot. There's just a question. What is the form of the rib cage when the person is stooping, like picking something from the ground? Will the rib cage be twisted?

[@manma6170]

ye it would m8 the reibs are attached to the spine

[@donatoliotino1872]

Damn. Promo is just so satisfying to learn from

[@kifanga]

In the premium version, do you show how much the model's spine actually rotates, in the image where the trapezius exaggerates the curve?

[@StanProkopenko]

kifanga I don't, sorry. But the Skelly App has pretty accurate spine rotations. www.proko.com/skellyapp

[@kifanga]

Stan Prokopenko Noted. Do you plan to update the anatomy apps at some point in the future with a female skeleton, or will they all be male Loomis proportions?

[@ivanchen9136]

kifanga If I recall correctly, male and female Loomis are basically the same, just female is less boxy?

[@izakvanlangevelde8597]

What puzzles me about the rib cage as a box, is that the front plane is confined to the costal cartilage, which is considerably narrower than the entire rib cage (according to Hale, the rib cage fits in a 2x2x1 box, so the front view should fit a square). So, the side planes are supposed to bulge out considerably, and, as a consequence, cannot be modeled as simple flat planes. Could proko shed some light on this?

[@ProkoTV]

Reading this, I'm not exactly sure what your question is. But I'd be happy to be of help!

[@izakvanlangevelde8597]

@@ProkoTV Let's see if we can sort this out. When you see the ribcage from the front, the costal cartilage is a relatively small part of the front view. So, for the rib cage as a box, the front plane of the box will be too narrow. To get a box with correct proportions, where does the 'missing width' go to?

[@ProkoTV]

@@izakvanlangevelde8597 You're right that the rib cage is not a perfect box, and the costal cartilage is indeed a relatively small part of the front view. The box analogy serves as a simplified way to understand the rib cage's structure and its planes. The "missing width" you're mentioning relates to the curvature of the ribs as they extend from the costal cartilage to the side and back planes. The side planes do bulge out, and this is where the full width of the rib cage is accounted for. When we simplify the rib cage as a box, we are essentially trying to capture the most basic structure and planes of the rib cage. In reality, the rib cage is more complex and organic in shape, with ribs curving from the front to the back. Hale's diagrams have the ribs existing above and below the boxes, so we know this is more of a baseline than a rigid rule to adhere to. While using a box to represent the rib cage can be helpful when first learning about its structure, it is essential to understand that it's a simplified model, and the actual rib cage has more rounded and complex forms.

[@izakvanlangevelde8597]

@@ProkoTV Thanks for sorting this out!

[@ShinoSarna]

The round shape isn't for me, but the box shape will be SO helpful for simplifying ribcage in perspective...
